This is a challenging relationship at best. In a romantic bond with each other, there are plenty of times when you look at one another -- or at yourself in the mirror -- and wonder exactly why you got into this in the first place. Problems arise from the very serious differences that exist between you as individuals.
There is an element of criticism and control between you; your partner always feels as if their individuality, who they are as a strong, vital human being, is being challenged by you -- or even put down. This could start in small ways -- perhaps when you were still just dating casually, you had conversations in which your opposing viewpoints come up again and again, and you might even have been able to laugh over your differences. Now that your relationship is something more long-term, your partner's sense of humor fades in the face of a feeling of burden and limitation that only grows with time. After a while, you aren't even able to see one another as individuals; instead, all you see when you look at one another is a list of grievances, of expectations that are disappointed, of needs that are never met. You must both take care not to let this heavy, troubled energy overpower the other, lighter, more positive aspects of your relationship. Work hard to accept each other -- and not to allow excessive criticism obscure your sense of who you are.
